Description
说 明 书 双面液晶显示装置及其背光模组 技术领域 Description: Double-sided liquid crystal display device and backlight module thereof
本发明涉及液晶显示技术领域， 具体地讲， 涉及一种双面液晶显示装置及 其背光模组。 背景技术 The present invention relates to the field of liquid crystal display technology, and in particular to a double-sided liquid crystal display device and a backlight module thereof. Background technique
现有的液晶显示装置中的背光模组主要分为直下式背光模组和侧入式背 光模组， 但不管是哪种背光源， 一般都设计为单面出光， 即只能搭配一块液晶 显示面板显示一幅画面。 随着社会的发展， 在诸如政府对外办公， 医院收费， 超市收银等地方需要 使操作人员同时看到屏幕的显示画面， 此时需要一台双面显示的显示器。 又如 网吧， 企业办公等地方， 一般是两人面对面坐着， 各自面前有一台显示器， 可 以将这两台显示器融合为一台双面显示器， 使它们共用一个背光模组， 再通过 电路分别控制这两块面板使其显示相同或者不同的画面。这样可以有效地降低 成本， 减少能耗， 减少占用的空间。 然而，传统的双面液晶显示装置一般是机械地将两个单面液晶显示装置组 合在一起， 即将两个单面液晶显示装置的背板合二为一， 这样不利于成本的下 降。 发明内容 The backlight module in the existing liquid crystal display device is mainly divided into a direct type backlight module and a side-in type backlight module, but no matter which kind of backlight source is used, it is generally designed to be single-sided light, that is, only one liquid crystal display can be matched. The panel displays a picture. With the development of society, in places such as government office work, hospital charges, supermarket cash registers, etc., it is necessary for the operator to see the screen display at the same time. In this case, a double-sided display is required. Another example is Internet cafes, corporate offices, etc., where two people sit face to face, each with a display in front of them, which can be combined into a double-sided display, so that they share a backlight module, and then controlled separately by the circuit. These two panels make them display the same or different pictures. This can effectively reduce costs, reduce energy consumption, and reduce the space occupied. However, the conventional double-sided liquid crystal display device generally mechanically combines two single-sided liquid crystal display devices, that is, the back plates of the two single-sided liquid crystal display devices are combined into one, which is disadvantageous for cost reduction.
